Design e Frontend

Generates 3 alternative Stitch prompts for A/B testing screen concepts — vary layout, visual style, or content while keeping the underlying information architecture consistent.

Evaluate UI designs against usability heuristics, UX laws, interaction patterns, interaction design principles, information architecture, and content quality. Conduct heuristic evaluations, structured design critiques, pattern-based reviews, posture analysis, excise audits, IA evaluations, and UX writing reviews. Provides specific, actionable feedback grounded in established principles rather than

Descompila arquivos de aplicativos Android (APK, XAPK, AAB, DEX, JAR, AAR) usando jadx ou Fernflower/Vineflower. Esta skill permite engenharia reversa de apps Android, extração de endpoints de API, rastreamento de fluxos de chamadas, análise de padrões de segurança e análise dinâmica com Frida para geração de bypass, análise de falhas e hooking em tempo de execução.

Uploads screenshots or mockup images into a Stitch project as new screens. Enables the "redesign from screenshot" workflow — import existing UI and then edit or convert.

Design meaningful interactions, microinteractions, animations, state machines, gesture patterns, error prevention, and product behavior. Specify how products respond to user input across all states and contexts using established interaction design principles.

Interactively co-build a software architecture using Simon Brown's C4 model (Context, Container, Component, Code). The skill detects the usage mode (greenfield design, retro-documenting from code or prose, review/explanation, update), runs a structured framing dialogue, proposes incremental drafts, and iterates until explicit user validation. Output format is negotiated (default Mermaid C4 + Markd

Run design sprints, manage handoff, establish team rituals, documentation standards, and design QA processes. Covers the operational side of design — how teams organize work, collaborate with engineering, and ship quality.

Updates an existing Stitch Design System's theme, tokens, or guidelines. Requires the asset name from create or list operations.

Visual vocabulary, design terminology, and prompt engineering strategy for Stitch. Reference this when you need layout pattern names, aesthetic style terms, color structure formulas, or device guidelines.

Converts Stitch designs into clean, platform-agnostic HTML5 + CSS — semantic markup, CSS custom properties for theming, dark mode via prefers-color-scheme, mobile-first responsive, zero framework dependencies. Works in browsers, WebViews, Capacitor, and Ionic.

Internal SuperBrain skill — run by the detached capture child to distill a session-event delta into routed Obsidian notes. Not for direct user invocation.

Analyzes a Stitch project's screens and synthesizes a natural-language DESIGN.md — visual atmosphere, color palette with hex values, typography rules, and Stitch-ready prompt snippets. Use this before stitch-loop or any multi-page build to establish design consistency.
